How can you determine the slope and the y- intercept of a line from a graph?

Answers

slope: Take two points from the graph, and do y-y, over x-x.

for ex. (1,2) and (2,4) do 4-2 over 2-1. your slope is 2/1= 2

y-intercept: find the one point on the graph that is exactly on the y-axis.

for ex. (4,0)= your y-intercept is 4

Answer:

y - intercept = - 18

Step-by-step explanation:

To find the y-intercept of the line

y + 4 = - 4 ( x + 3.5 ) ,

We can transpose the equation into the y = mx + b formula where b = y - intercept.

y + 4 = - 4 ( x + 3.5 )

y + 4 = ( - 4x ) + ( - 14 )

y + 4 = - 4x - 14

y = - 4x - 14 - 4

y = - 4x - 18

b = - 18

Therefore:

y - intercept = - 18

What is 0.04 times 7.6? Using ur work

Answers

Well, you'll multiply regularly, then move da decimals to the left 3 times, because if you add the amount of decimal places in 0.04 and 7.6, (2 + 1), it equals 2, but so 0.04 times 7.6 = 0.304

A dentist was making note of his upcoming appointments with different aged patients and the reasons for their visits.The probability that an appointment is with patients over 60 years old is 0.2, and the probability that it is for a broken tooth is 0.4.
What is the probability that a randomly chosen appointment is with patients over 60 years old or is for a broken tooth if those are independent events?
